So far working ok. May be a little thin so time and use will tell the story. Used to buy a more expensive mat from American Floor Mats which had a "lifetime guarantee" but found that they fell apart after a year of use and they didn't make good or even respond to my letters and photos of the mat having torn apart so decided to try Staples at a less expensive price and seeing if I get a better result. Have had it about two weeks and so far it's doing OK.
Person involved went out of the normal way to provide help in selection and in checking out and then to getting the item out of the store for transportation.
This mat protects our carpet under the office chair which has 5 wheels. This is our second purchase the first mat lasted several years so the quality is very good.
This particular chair mat is really only good for light duty. I do know weigh very much I have an office chair on rollers; and the rollers mold themselves into the plastic mat. Not easy to move around once I sit. And the carpet that is under the mat is heavy duty indoor/door (not plush at all).
